Learning Goal: To practice Problem-Solving Strategy 10.1 Conservation of energy problems. An ice cube of mass 50.0 gg can slide without friction up and down a 25.0 degreedegree slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 0.100 mm . The spring constant is 25.0 N/mN/m . When the ice cube is released, how far will it travel up the slope before reversing direction

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
